双品类存货组合的质押率研究   总被引:1,自引:0,他引:1  
孙朝苑  韦燕 《财经科学》2011,(10):117-124
本文假设静态质押模式下组合质押存货的价格变动相互独立并服从对数正态分布。在此基础上,构建质押率决策模型并对其影响因素进行分析。研究结果表明:存在使银行期望利润最大化的最优质押率;质押率与银行贷款利率呈同向递增趋势,随着贷款周期的增加呈现先增加后减小趋势。  相似文献

货币替代和反替代对我国货币政策独立性的影响   总被引:1,自引:0,他引:1  
货币替代和反替代会通过多种渠道影响一国货币政策的独立性。我国当前同时存在着货币替代和货币反替代,其中货币替代的程度在不断下降,而货币反替代的程度则不断增强。通过构建包含货币替代和货币反替代的粘性价格货币模型,本文运用回归方法检验了货币替代和货币反替代对我国货币政策独立性的影响程度。结论是,货币替代和货币反替代都会影响到我国的货币供给,进而会降低我国货币政策的独立性,但货币替代的影响更加强烈。  相似文献

独立性是独立董事制度的灵魂,没有独立性,独立董事作为监督者的作用将不复存在。独立性包括形式上的独立和实质上的独立两个方面。形式上,除担任董事外,独立董事与公司不能有其他形式的联系。只有形式独立是不够的,还必须保证实质独立,独立董事应以第三者立场发表意见,不受重要股东,公司经理层及其他利益相关者的影响,客观公正的行使职责。我国上市公司引入独立董事制度虽然有十多个年头,但是独立董事独立性的缺失使得这一制度实施的实际效果并不是很理想。  相似文献

中外文学作品中的女性自由解放主题是时代发展、妇女思想进步的产物,其中著名的“新女性”一一一“娜拉”和“子君”,更是以其鲜明的艺术形象,成为当时社会中妇女解放的“号召者”,至今仍富有现实意义和劝告意味。娜拉和子君的形象差异原因分析,体现了妇女解放斗争活动对“精神自由”和“经济独立”两大方面侧重点的差异,在不同时代、不同国家的作品中是各有不同强调的,这也帮助我们更客观的审视两位叛逆女性在妇女解放历程中呈现出的时代意义。  相似文献

上市公司审计委托制度的弊端分析及解决对策   总被引:1,自引:0,他引:1  
邵丽 《特区经济》2010,(6):107-108
我国现行上市公司审计委托制度存在的固有缺陷是审计的独立性严重受损。由公司管理层代行所有者的审计委托权,使审计人与被审计人的利益相关联,造成了财务造假屡屡发生,解决这一问题的根本途径是建立新的审计委托制度。  相似文献

Folklore has it that a very simple supervised classification rule, based on the typically false assumption that the predictor variables are independent, can be highly effective, and often more effective than sophisticated rules. We examine the evidence for this, both empirical, as observed in real data applications, and theoretical, summarising explanations for why this simple rule might be effective.  相似文献

Operating multiple channels, in store as well as non-store, allows a retailer to cater to the different shopping motives of its customers. This research into the buying behavior of 525 customers of a multi-channel retailer that operates five channels in Germany shows that most customers use only one channel within a buying process, selecting the channel that best satisfies their shopping motives in each situation. Based on exploratory qualitative and quantitative research, this study identifies five shopping motives: “recreational orientation”, “convenience orientation”, “independence orientation”, “delivery-related risk aversion” and “product- and payment-related risk aversion”. In the majority of the store channels examined in this study (chain stores and bakeries), single-channel users primarily look to satisfy emotional and social needs. Single-channel users of non-store channels (catalogue and online-shop) look for convenience and strive for independence. Multi-channel users, who obtain their information from the online-shop and then make their purchase in the chain store, are combining the independence of online-shop information with the reduction of risks associated with buying products in the chain store. These findings can be used to develop recommendations for managing the individual channels.  相似文献

Several authors in the literature have attempted the quantification of the concept of stochastic dependence for bivariate distribution. Two weighted rank tests for testing independence against a weighted contamination alternative is proposed and their distributional properties are studied. We also derived a locally most powerful rank test for the alternative setting. The rank tests proposed are shown to be asymptotic locally most powerful for specific distributions.  相似文献

WARWICK FUNNELL 《Abacus》1994,30(2):175-195
The principles of state audit, in particular conceptions of independence, adhered to today in the major Westminster democracies originated in the British state audit reforms of the nineteenth century. State auditors prior to the nineteenth century were not expected to be independent of the executive. Instead, state audit was recognized as an executive function to be under the direct control of the executive. For a brief period in the mid-nineteenth century, parliament was able to take advantage of a succession of weak governments to redirect the loyalties of state audit from the executive to the legislature. Although parliament wanted to be served by a state auditor who would keep it informed of executive spending, it did not alter the dominance of the Treasury over state audit. The executive sought to sustain through a discourse of independence the perception that the controls exercised by the executive over the state auditor did not constitute either a threat to audit independence or result in capture of state audit by the executive. The discourse constructed the image of state audit as a function which was able to work unimpeded and independent of the executive despite a legislative framework which contained significant financial, procedural and staffing controls.  相似文献
